Replication Schemes for Efficient Service Profile Management in Personal Communication Service Networks

摘要

In the future mobile network, it is expected that per-user customized services are widely used. To provide personalized services for each call, per user service profiles are frequently referenced, so the centralized Intelligent Network scheme can be a bottleneck. In this paper, we propose four service profile replication schemes for efficient service profile management. According to the profile download and upload timing and the usage of the frequent zone concept, the schemes include Follow-Me-Replication-Unconditional (FMRU), Follow-Me-Replication-Unconditional on-Demand (FMRUD), Follow-Me-Replication-Conditional (FMRC) and Follow-Me-Replication-Conditional on-Demand (FMRCD). These are described and compared in the view of network traffic costs. Performance results indicates that.
